A person's teeth can relate to your feelings about that person's:
Health and well-being
Ability to do things for oneself or handle tasks in one's own life
Ability to articulate and express oneself
Someone having problems with teeth, such as teeth falling out or having cavities, can represent feeling, fearing, or imagining that all is not well with that person, or perhaps that the person is not expressing themselves as well as you think they should.

Possible dream symbol meanings in the dream dictionary are suggested. No "standard meanings" exist because dream meaning is subjective and specific to the dreamer.
